A Range Bar Chart with a second series set to Point.



Overview

The Range Bar Chart displays a bars for each dimension value ranging between a start value and an end value. This chart is commonly used as a simple form of Gantt chart, where bars represent the beginning and end of activities or tasks along a time axis. The axes are switched on this chart by default so that the Y axis is horizontal and the X axis is vertical. See: How to create a Gantt Chart

Tip: Combine a Range Bar Chart with series set to Point to display markers representing milestones or other important dates, as shown in the example at right.

This chart is different from other charts in that the Y axis can display values that are not numeric. When you add a dataset to this chart, the Data Settings Configuration wizard will ask for Bar Start and Bar End dimensions, which can be DateTime values. (KPIs define measures and contextual metrics that must be numeric, so you must use a dataset to display DateTime values along the Y axis.)

  • This chart is represented by the DashboardRangeBarChart class, which has common chart properties and interactions.
  • This chart accepts two metric values from each KPI or contextual metric added to it, for each X axis dimension value. From datasets, Bar Start and Bar End dimensions are requested, which can be either metric values or date/time values.
  • In another rectangular chart, make a series Range Bar by setting the Chart Type property of the series to RangeBar.
  • When a series is Range Bar, its type and properties are those of the DashboardBarDataSeries class.

Features

Range bar chart series share settings with the Bar Chart, including Draw Side By Side. Set it to False to overlap bars of different series. Set it to True to show each series separately, for example to clearly see when actual task dates go longer than scheduled.
